Doctors say she’s ‘overwhelmed’ by her bipolar disorder and needs to re-energize before her next projects!

Catherine Zeta-Jones shocked her fans when it was revealed she spent five days in a Connecticut mental health facility, after admitting herself on April 6 to manage her Bipolar II Disorder. But perhaps most shocking was that her stay in treatment was so short. HollywoodLife.com spoke exclusively with a mental health specialist to understand why her stay was so brief, and what treatment likely focused on.

“She most likely went in for only five days because of time constraints for her in her career,” says Dr.Jeff Gardere, a psychologist who has worked with bipolar patients and is a chief contributor to Healthguru.com. “She has to give the impression she’s not incapacitated so it doesn’t affect her being insurable in Hollywood and I appreciate and respect that she’s so open about it.”

Dr. Gardere speculated her fatigue from worrying about husband Michael Douglas and his illness may have lead her to seek medical attention.

“She’s going in for a tune up,” he said. “She’s overwhelmed and she’s exhausted. Maybe she is really depressed right now and doing this and sending her home says she’s not as bad as someone must be to go away for much longer.”

We hope Catherine got all the help she needed to get through her upcoming film projects!
